Quantum ESPRESSO Theory Details: taller than the screen and cannot be resized #351

Found 2026-10-15 on niobium (Linux, test-912 build). With the DFT+U and dispersion boxes added, the QE Theory Details dialog does not fit on the screen, and it cannot be resized. Codereg dialogs should scroll inside EccePanel when their content is taller than the display (#189, docs/claude/wx-viewer/windows-fit-small-screens-via-fittodisplay.md). Check why qetheory.py escapes that, and whether other long Details dialogs do too (tests/apps/smallscreen_test.py). Not release-critical for 9.2.0.
